I made a css layout and I wanna know how do I set it up/install it?

you made a css layout as in you coded it or as in you made it in a graphic program?

if made in graphic program:
- code it in notepad with css
- upload it to your server
- done

if made as in coded:
- upload it to your server
- done

:)
